To all 'whom 'it may concern.'

Be it known that l, NATHANv M. Lownn, a citizen of the llnited States,and residentot Pittsburgh, county of Allegheny, and State ofPennsylvania, have invented certain new and uset'ul linproveinents `inFuel-Distributers, of which the following is a speeitication, and whichare illustrated in the ac-y companying drawings, forming a part thereof.

rlhe invention relates to device-s used in connection with mechanicalstokers for distributing fuel, such as coal, within a lirebox; itsobject beingr to provide for the even distribution 0i the fuel over-thegrate.

The invention consists of a tubular body having an open end andadv'apted to be; horizontally positioned Within the hre-box wall, andbeing provided With nozzles at its inner end adapted to discharge jetsof luid, such as steam or air, obliquely backward tor the purpose otdetlecting` a portion of the fuel impelled through the tube by anysuitable means to` spread it upon the grate at the end of the lire-boxat which thedistributer is located, and especially to insure the depositoi' an ample supply of fuel upon the corners ot the grate; such nozzlesbeing located at the top or bot-tom ot the tube, or

at both ot these positions.

In the drawings showing` e preferred torni of construction- Figure l isa plan view ot a distributor;

Fig. 2 isl a longitudinal vertical section, partly in elevation; and

Fig. 3 is a rear end view thereof.

The distributor preferably takes the form of a. tube 29, having a fiatbottoni 30 and being adapted to be secured within an opening in the Wallof the lire-box, there being; shown as a convenient means for suchattachment an aperture 3l in. the upper portion ot' the tube adjacentits rear end Within which a retaining hook may be engaged.

The tube 29 is open at its inner end to permit theiree discharge of fuelinipelled therethrough by any preferred ineens, and in theembodimentshown is also open at its rear end to receive the fuel fromany suit able sourcebt' supply, suoli as an elevator or a hopper,thougli itis immaterial to the present invention "whether, the receivingopening be at'the end or laterally.

At the forward, end of the tube 29 there is a forwardly extendingtia-nge 82, preter- Specification of Letters Patent. PatQni-e Sept. 27,1921.

ably formed integral with the body, as shown, the lower face of thisflange being given any desired conlivuration but is prel erably dat, asshown. portion of the fuel which may be impelled through 'the tube atconsiderable velocity will strike thevunder face of the flange 32, andbe thereby directed downwardly' and scatteredover a zone ot'Aconsiderable width.

.Depending from the flange 32 is a nozzle 33, here shown as in theforznof a hollow integral boss, this nozzle being provided with a.plurality of discharge openings, as 34, which are directed backwardly'and downwardly, and some of theni oblique to the direction in which thefuel is advanced through the tube. Fluid under pressure is supplied tothe nozzle 33 through a suitable duct 35, which in the disclosed form ofconstruction is cored in the top'wall of the tube. there being provideda suitable opening at which a service pipe may be attached.- For thisletter purpose there is` shown such openings at 36, 37, and 38, any orall of which may be used.

A similar nozzle 39 issecured at the for; ward end ot the bottom thetube. If de;- sired, this nozzle may tale the form' of au. elbow nipple,as shown,"screwed `into the end ot' the tube 29 to 'communicate with acored duct 4:0," supplied with fluid under pressure through suitablepipes connected with its reni* end, as at il or 42. Whatever may be itsspecific forni the nozzle 39 projects upwardly, above the floor orbottom 30 oi the tube 2S), and is provided with a plu` rulity otlaterally bcluvurdly directed openings, as 43, adapted to dischargefluid jets which will dcliect. portions of the dvancing i'uel vto thecorners ot the fireoX. i

Various embodiments ot the invention moy be made which will come withinits scope, the essential feature of which is the location ot thescattering jetsat' the inner end of a fuel induction passage.

l clainius .my invention- 1. ln a fuel distributer, an open ended tubeadapted to be disposed in a substantially horizontal position andthrough which fuel may be ilnpelled, und a fluid-discharging nozzle atthe upper side of the forward end of the tube and having its outletports backwardly and downwardly directed'.

2. ln e fuel distributor, an open ended tube adapted to he disposed in asubstantially horizontal position and through which fuel may beimpelled, and a fluid discharging` nozzle at the upper side of thel'orward end of: the tube and having its outlet ports backwardly,downwardly and laterally directed.

3. A distrihuter tube having` a lat bottom and an open discharge end andadapted to be horizontally positioned and having a flange projecting`from the upper portion of its discharge end, a fluid nozzle projecting'upward at the forward end of its bottom and discharging obliquelybackward1 and a fluid nozzle depending from the flange and disA charginghaclnvardly.

4. A distributor tube having a flat bottoni and an open discharge endand ada pted to be horizontally positioned and havingl a flangeprojectingl from the upper portion of its discharge end, a fluidnozzleprojecting upward at the forward end oi its bottom and disnsem vcharging obliquely backward, and a fluid nozzle depending from thellange and discharging obliquely backward.

A'luel distributor comprisingr a passage through which fuel may beimpelled, and vla fluid discharging nozzle located at the inner end ofthe passage and adjacent its upper portion and l'iaving jet openingsdirected obliquely baclm'ard. l

A fuel distributor coniprisinga passage through which fuel may beimpelled, anda fluid nozzle located beyond the delivery end of thepassage and having jet openings directed obliquely backward.

T. A fuel distributor comprisingr a passage through which fuel may beimpelled, 4and a fluid nozzle 'located beyond the delivery endj of thepassage and depending into the line lofthe path ol fuel iinpelledthrough such )assafe and havino v'et oieninefs directed Pi l ohliquelybackward.
